Is there a maximum length of phone cable that should be run from the Voip router to the phone? Can some of these routers drive the audio signal further than others? I wonder about that because, some of my phone cabling is probably longer than it should be.. i think I have Category 1 phone cabling though it may be Category 2. The reason I ask is that sometimes, for example today, an existing phone call is inexplainably dropped (without either end hanging up). And other times one or more of my phones have no dial tone. But then again, often, all the phones work fine (without any changes to the phone or network cabling or network equipment ). |

josephsw, the inconsistency in your experience with your homewiring can be caused by a number of issues. However, if they are cat1 or cat2, I'd suggest that they are probably caused by faulty wiring that is causing greater resistance than can be handled by your rt31p2. But that's just one thought. How old is the wiring? Any chance that you can pull cat5 wiring instead? Supposedly much better wiring. Otherwise, I think these inconsistencies are here to stay. I know each type of wiring has a max length for signal consistency but I don't know much about cat1 or cat 2. I know cat 5 is 100 meters or roughly 320 ft or something like that. Check google to see the max length. |

Cat 5 specs you're refering to are for Ethernet, not Phone signals. Cat 3 is good enough for any household phone install. Sounds more like a bad cable,connector or jack. |

You could always try using a new short cable from the Voip Adapter and see whether you encounter the same problems |

Thanks for the replies. I think I found the culprit:
DSL Filters.
When I removed the DSL filters off my home phones, voice markedly improved and the phone-dead problems seem to have gone away.
So in a sense it was bad cabling: DSL filters cut off some of the signal bandwidth and the Linksys router is probably set to use the entire phone cable bandwidth like an ordinary Telco.
When I switched to Verizon FIOS for my broadband internet, I neglected to remove those filters. |
